Edit:
A couple use cases that I'm looking to satisfy here:
1. My editor allows certain features to execute on connections, so it would make sense to CTRL-A to select everything then run a feature which executes on all selected connections.
2. Connections in my editor can exist in a "disconnected" state in which they are dangling and connected to anchors which cannot be deleted, unless the connection itself is deleted or the connection is reconnected to a valid target. In this case, using CTRL-A and then running the delete feature will remove all valid targets/sources of the connections in my diagram and leave me with "dangling" connections since the connections themselves were not selected and queued for deletion.]]>Craig Petre2012-04-12T16:26:17-00:00Re: Connection select all questionhttps://www.eclipse.org/forums/index.php/mv/msg/328089/843814/#msg_843814
currently CTRL-A works as designed. I think this behavior is suitable for 95% of our customers.

But on the other side I understand your ideas/requests. Perhaps we can make the action behind CTRL-A more configurable (via the IToolBehaviorProvider)
